Might be a bad ground ... there are 3 wires on the gauge ...
ground .. jump this direct to your battery -ve.
12V ... jump this direct to your battery +ve
and the sensor ... run a replacement /temp wire
that way you can replace the wires one at a time and figure whats causing the excessive sweep. If it still does it then the gauge of sensor are faulty. Sensor can be tested with a multi meter for resistance. Gauge I'm not sure.
Many people move to VDO at this point!
